I agree the front one does appear to be male need a better view of the second to determine. See the pinkish belly on Fishbowlings pair that is a sure sign of a female. While not a great shot you can still see the rosey belly.
Okay, had to lure her out with food to get a better shot. She is not nearly as phone camera-friendly as her mate; I felt like I was one of those camera guys on the "Planet Earth" crew camped out for days to get 15 seconds of video.
